Patrick Lockhart made his dramatic entrance to Salem when Jennifer Horton literally ran into him with her car. They were both taken to the hospital and Jennifer felt guilty because Patrick had no insurance and no place to stay. She paid his medical bills then offered him a home in her garage apartment, which he gratefully accepted.

Since moving to Salem, it's become obvious that there's more to Patrick Lockhart than meets the eye. Jennifer and all of her friends were suspicious when they learned that his mother was housekeeper Bonnie. Patrick continued to live in Jennifer's garage apartment and took care of her throughout her difficult pregnancy, even mysteriously saving the baby with the help of an antique doubloon.

When Jennifer left to find Jack, Patrick was determined to find her. He and Hope took off in a cargo plane and followed Jennifer to the remote tropical island where Tony DiMera was holding all of the "victims" of the Salem Stalker. Patrick and Hope ended up in the jungle, where Patrick delivered Jennifer's baby, Jack Jr. They ended up in Tony's compound, where Patrick's history as a DiMera operative became clear. He even helped DiMera keep some of the Salemites hostage. When push came to shove, however, he helped his new friends escape.

Patrick returned to Salem, where he returned to his old life. He grew closer to Billie and to Hope, both of whom trusted him, but Bo did not. He and Billie briefly hooked up, but they both seem interested in others, namely Bo & Jennifer. Is Patrick still working for the DiMeras?
